Airworthiness Directives; Dassault Aviation Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for all 
Dassault Aviation Model MYSTERE-FALCON 50 airplanes. This proposed AD 
was prompted by a determination that more restrictive maintenance 
requirements and airworthiness limitations are necessary. This proposed 
AD would require revising the maintenance or inspection program, as 
applicable, to incorporate new and more restrictive maintenance 
requirements and airworthiness limitations. We are proposing this AD to 
address the unsafe condition on these products.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2018-0026, dated January 30, 2018 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for all Dassault Aviation 
Model MYSTERE-FALCON 50 airplanes. The MCAI states:

    The airworthiness limitations and certification maintenance 
instructions for the

[[Page 21954]]

Dassault Myst[egrave]re Falcon 50 aeroplanes, which are approved by 
EASA, are currently defined and published in the Dassault 
Myst[egrave]re Falcon 50 Aircraft Maintenance Manual (AMM) chapter 
5-40. These instructions have been identified as mandatory for 
continued airworthiness.
    Failure to accomplish these instructions could result in an 
unsafe condition [i.e, reduced structural integrity of the 
airplane].
    Consequently, EASA issued [EASA] AD 2016-0067 [which corresponds 
to FAA AD 2017-09-03 Amendment 39-18865 (82 FR 21467, May 9, 2017) 
(``AD 2017-09-03'')] to require accomplishment of the maintenance 
tasks, and implementation of the airworthiness limitations, as 
specified in Dassault Myst[egrave]re Falcon 50 AMM chapter 5-40 
Revision 23.
    Since that [EASA] AD was issued, Dassault issued Revision 24 of 
the Dassault Myst[egrave]re Falcon 50 AMM chapter 5-40, which 
introduces new and more restrictive maintenance requirements and/or 
airworthiness limitations.
    For the reason described above, this [EASA] AD retains the 
requirements of EASA AD 2016-0067, which is superseded, and requires 
accomplishment of the actions specified in Revision 24 of the 
Dassault Myst[egrave]re Falcon 50 AMM chapter 5-40 * * *.

    You may examine the MCAI in the AD docket on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2018-
0394.

Relationship Between Proposed AD and Certain Other ADs

    This NPRM would not supersede AD 2017-09-03. Rather, we have 
determined that a stand-alone AD would be more appropriate to address 
the changes in the MCAI. This NPRM would require revising the 
maintenance or inspection program, as applicable, to incorporate the 
new maintenance requirements and airworthiness limitations. 
Accomplishment of the proposed actions would then terminate all 
requirements of AD 2017-09-03. Accomplishment of the proposed actions 
would also terminate all requirements of AD 2010-26-05, Amendment 39-
16544 (75 FR 79952, December 21, 2010) (``AD 2010-26-05'') and AD 2012-
02-18, Amendment 39-16941 (77 FR 12175, February 29, 2012) (``AD 2012-
02-18''), for the Dassault Aviation Model MYSTERE-FALCON 50 airplanes 
specified in those ADs.

Related Service Information Under 1 CFR Part 51

    Dassault Aviation has issued Chapter 5-40, Airworthiness 
Limitations, of the Dassault Falcon 50/50EX Maintenance Manual, 
Revision 24, dated July 2017. This service information describes 
instructions applicable to airworthiness and safe life limitations. 
This service information is reasonably available because the interested 
parties have access to it through their normal course of business or by 
the means identified in the ADDRESSES section.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type designs.
    This proposed AD requires revisions to certain operator maintenance 
documents. Compliance with these revisions is required by 14 CFR 
91.403(c). For airplanes that have been previously modified, altered, 
or repaired in the areas addressed by this proposed AD, the operator 
may not be able to accomplish the actions described in the revisions. 
In this situation, to comply with 14 CFR 91.403(c), the operator must 
request approval for an alternative method of compliance according to 
paragraph (j)(1) of this proposed AD. The request should include a 
description of changes to the required actions that will ensure the 
continued damage tolerance of the affected structure.

Differences Between This Proposed AD and the MCAI or Service 
Information

    The MCAI specifies that if there are findings from the 
airworthiness limitations section (ALS) inspection tasks, corrective 
actions must be accomplished in accordance with Dassault Aviation 
maintenance documentation. However, this proposed AD does not include 
that requirement. Operators of U.S.-registered airplanes are required 
by general airworthiness and operational regulations to perform 
maintenance using methods that are acceptable to the FAA. We consider 
those methods to be adequate to address any corrective actions 
necessitated by the findings of ALS inspections required by this 
proposed AD.

Costs of Compliance

    We estimate that this proposed AD affects 250 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:
    We have determined that revising the maintenance or inspection 
program takes an average of 90 work-hours per operator, although we 
recognize that this number may vary from operator to operator. In the 
past, we have estimated that this action takes 1 work-hour per 
airplane. Since operators incorporate maintenance or inspection program 
changes for their affected fleet(s), we have determined that a per-
operator estimate is more accurate than a per-airplane estimate. 
Therefore, we estimate the total cost per operator to be $7,650 (90 
work-hours x $85 per work-hour).

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. Subtitle VII: Aviation Programs, 
describes in more detail the scope of the Agency's authority.
    We are issuing this rulemaking under the authority described in 
Subtitle VII, Part A, Subpart III, Section 44701: ``General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.
    This proposed AD is issued in accordance with authority delegated 
by the Executive Director, Aircraft Certification Service, as 
authorized by FAA Order 8000.51C. In accordance with that order, 
issuance of ADs is normally a function of the Compliance and 
Airworthiness Division, but during this transition period, the 
Executive Director has delegated the authority to issue ADs applicable 
to transport category airplanes to the Director of the System Oversight 
Division.

Regulatory Findings

    We determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would not 
have a substantial direct effect on the States, on the relationship 
between the national Government and the States, or on the distribution 
of power and responsibilities among the various levels of government.
    For the reasons discussed above, I certify this proposed 
regulation:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;

[[Page 21955]]

    2. Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979);
    3. Will not affect intrastate aviation in Alaska; and
    4. Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
